1980-11-28 Matthew Saad Muhammad w co 4 (15) Lotte Mwale, Sports Arena, San Diego, California, USA - WBC. Referee: Tony Perez. Mwale (172½) made a good start when boxing the champion on even terms, but towards the end of the third round he was stunned by a big left hook and somehow survived the two-handed punches coming his way to last out the session. Chasing Mwale down with right and left swings to the body in the fourth, Muhammad (175) eventually found a tremendous left uppercut to the jaw that sent the Commonwealth champion down to be counted out on the 2.25 mark. Afterwards, Muhammad said that the finishing blow was probably the hardest that he had ever thrown.
